Monaural Sound Source Separation by Perceptually Weighted Non-Negative Matrix Factorization - Demonstrations

The following audio examples demonstrate the performance of a perceptually weighted non-negative matrix factorization algorithm in one-channel sound source separation.

The signals are generated by separating the original 7-second excerpts into components, the number of which was set by hand (from 2 to 8 components were used). The components were clustered to sound sources by hand. Naturally, manual clustering may not be used in the final application. These examples are used just to demonstrate the possible outcome of a separation system.
